THOMAS S. FOX, OF BROOKLYN, NEW YORK.

PRINTING APPARATUS.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application filed December 28, 1907. Serial No. 408,445.

To aZZw/zom it may concern:

Be it known that I, THoMAs S. Fox, a citizen of the United States, residing at 100 Park Place, Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Printing Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in printing apparatus and is an improvement upon the apparatus set forth in my patent application bearing Serial No. 232,999, filed November 16, 1904-.

The invent-ion has more particularly to do with the use of marking mediums such as printing films as used in the preparation of printing surfaces of copper, zinc, stone or the like.

Referring to the accompanying drawings, Figure 1 is a side view partly in section of my complete apparatus showing a convenient form of adjustable stand upon which a table or platform of the mechanism may be mounted. Fig. 2 is a plan view looking down upon the apparatus. Fig. 3 is a perspective view partly in section showing the clamping attachments and superstructure of the apparatus. Fig. 4 is a perspective View partly in section showing a bar and clamping device adapted for holding the printing film. Fig. 5 is a perspective view partly in section showing a modified form of part of the superstructure of part of the apparatus. is a View parly in section showing a binding attachment to prevent rotation of the operating board. Figs. 7 and S are plan views showing the construction of part of a protractor. Fig. 9 is a perspective view partly in section showing roller bearing for supporting the rotatable operating board and frame for scale records. Fig. 10 is a perspective view showing a form of rest adapted to support a film while the same is being inked. Figs. 11 and 12 are views showing angular bearings upon which a rotatable operating board may be moved at right angles to its axis. Fig. 13 is a cross section of a channel-way or groove and binding pin adapted to hold the work in position, and Fig. 14 is a cross section of the modified form of adjusting device shown in Fig. 5 which may be used with the apparatus.

10 is the base or platform of the apparatus and is preferably mounted upon a suitable adjustable support or table such as 10 adapted to be raised or lowered by the pin 11 in the usual manner and adapted to be tilted at any angle upon the spindle 12 and held in a fixed position by a binding cam in the usual manner.

28 is a metal cross adapted to support the rotating operating table and provided with a central hearing or axis mounted upon the platform 10 upon which the same may rotate and also provided With angular bearings 2626 shown in section in Figs. 11 and 12. One end of one arm of the cross 28 is to indicate in degrees upon the card 53 the position of the rotatable operating board 11.

This operating board 11 has preferably an hexagonal periphery and is provided with angular projections 2727 seated in the angular bearings 2626 of the metal cross 28. A frame 52 may also be provided at the end of one of the other arms of the metal cross 28 and adapted to receive scale or record cards 53 prepared for use with the films to be used with the apparatus. At the opposite end of the cross from the scale card, there is a projection 44: attached to a cleat 121 fastened to the operating board 11 as shown in Fig. 7. Said long needle or pointer -l9 is preferably mounted on the pin 50 close to the same end of the cross 28 and is also provided with a projection 51 and said projection is connected with the projection a l by the spring so that when the winged nut is turned in one direction the spring end of the needle 49 follows the end of the cleat 121 and the movement of the board 11 is indicated on the card 53 by the pointer 1-9. V hen the winged nut 30 is turned in the reverse direction the projection 44 is moved away from the projection 51 to which it is attached by the spring 15 and the needle 19 again reads in the opposite direction on the card 53. The winged nut 30 is preferably mounted on the screw 122 fastened to the cleat 123 attached to the operating board 11' and surrounded by the spiral spring and seated in the bearing 26. The spiral spring 60 is under compression, always tending to force the board 11 away from the bearing 26, so that every rotary movement of the winged nut 30 imparts a corresponding longitudinal movement to the board 11. 47-47 are binding posts adapted to carry roller bearings 3636 fastened therein by the binding screws 4r848. The little roller 136 may be constructed of rubber or may be reinforced by a spring in the usual manner for taking up lost motion which may be caused by the springing, warping or wearing of the board or of any of the parts. If a spring is used instead of the rubber a spiral spring may be employed in combination with the usual telescopical hearing.

The scale cards 53 are so arranged that they may he slipped in and out of the frame 52 and are so graduated that each card is adapted for use with a differently designed frame, in other words, where a frame is employed having one hundred lines to the inch, a record card will be used provided with spaces corresponding with the movement of the needle 19 when the operating platform 11 has been longitudinally moved by the winged nut 30 one one hundredth of an inch, and it will be observed that owing to the posit-ion of the point of balance 50 of the needle, the reading point of the needle will move a greater distance along the record card than the board 11 will move in the same direction at each twist of the winged nut 30, so that it will be a very easy matter for the operator to determine, by reference to the scale card, how much adjustment of the winged nut 30 will be required in order to lay one or more lines between the lines marked by the film which are one one hundredth of an inch apart. Of course it will be readily understood the more the scale card 53 is marked off and subdivided in accordance with the scheme of measurement laid down, the more accurately the operator can predetermine the mathematical composition of the design to be produced by the apparat-us.

1212 are clamps adapted to engage the base or table 10 and are fastened thereto by the binding screws 54.5-1. Where the bases of these clamps are suficiently large and weighted in metal, they may be used as stands independent of the table, to be removed and replaced as ordinary weighted members. The clamps 1212 are adapted to support the standards 13-13' which may be raised or lowered by the binding screws So-55 and which in turn also carry the clamps 5656.

14L is a supporting bar resting in the clamps 56-56 and may be retained therein by the binding screws 6161. This bar may be moved in the clamps and a suitable scale such as 97 may be marked thereon or attached thereto for the purpose of indicating the movement of said bar relative to said clamps. Standards 1919 may also be fastened in the clamps 1212 by the binding screws 7777 and are preferably connected by the bar 20 to serve as a reinforcement and support. Upon the bar 14, which for convenience is shown in angular cross section but which may be an ordinary circular bar, are mounted the clamps 100100 fastened thereto by the binding screws 6363. These clamps 100100 may be provided on one side with the plates Get-64 provided with springs 6666 and may also be pro vided with guide pins (ST-67 and 68-68 to prevent lateral shifting of the plates.

69-69 are pintles or bearings adapted to engage the ends of the bar 24: adapt-ed to carry the printing film, or said pintles may engage suitable clamps or cleats attached to said printing film in the usual manner, and as shown in my former application previously referred to.

The tops of the clamps 100100 may be provided with bearings '1'O-70 and binding screws 7171 adapted to engage and retain a rod or bar 72 which may be inserted as a substitute for the bar 24;. This bar 72 may be provided with longitudinal slots or grooves 125 and with transverse circumferential slots or grooves 126. When the bar 2a is used clamps 73-75 are bound thereto by the binding pins 7 1-74! and provided with extension clamps 16-16 adapted to engage the printing frame 75 by turning the binding screw 76-76. The bar let may also be provided with clamps provided with brackets 7878 held thereto by binding screws 79-79'. T 0 these brackets may be fastened aframe work or backing 80 adapted to form a rest or pad for the printing film 23 when it is thrown back upon the same for inking. WVhen the bar 72 is used in place of the bar 24 brack ets 81 may be employed in place of the brackets 78 to support the rest or pad 80 and may be fastened to the bar 72 by the binding screw 82. The printing film may also be fastened to the bar 72 by the clamps 8-3 held by the binding screw 8-1. The binding screws 71-82 and 84: are adapted to engage the circumferential slots or grooves 126 and the longitudinal grooves 125 so that the bar may be allowed to r0- tate independently of the parts, or the parts to rotate upon the bar as found preferable in the use and adjustment of the apparatus. Of course it will be understood that by loosening the binding screws 63-63 and tightening the binding screws 71'. 1 upon the bar 7 2, the printing film and its pad or rest on the bar 72 may be shifted transversely and simultaneously at the will of the operator along the bar 14, whereas if the bar 2% is used, or if the printing frame is supported directly by the pintles 6969, and the support 80 is mounted on the bar 14, the bar 1% must be moved transversely as well as the bar 24, in order that the print-- ing film and its pad or rest may be shifted and used simultaneously. The bar 14 may be provided with a suitable scale such as 97 for measuring its transverse movement relative to the clamps l0O-100. The movement of the bar 24 may be measured by the scale 96 upon the periphery of the head 96 of the pintle 69 which is provided with screw threads 95 engaging a threaded bearing in the clamp 64L. The lateral movement of the bar 72 may be controlled and measured by the little worm gear 180 on the binding screw 71, said worm gear meshing with the worm gear 131 011 the bar 72 and by providing a scale such as 140 upon the bar 72, the amount of movement of same may be easily determined.

The rotation of the revoluble operating table 11 is controlled by the binding screw 93 in the end of the cross 28 which tends to bind said cross to the top of the protractor 32 when it is screwed down. It will be readily observed that the superstructure of the apparatus is adapted for use on an ordinary table or counter. In this event the clamps 12 might serve as weighted members and the superstructure would be moved at a suitable angle over the work, or the work itself might be moved beneath the superstructure.

The channel-Ways 4L5 of the rotatable operating table are formed by the parallel plates between which a flat headed binding screw may be inserted and engage the little nut is within the channel so as to bind the metal plate 135 or similar article.

Various modifications may be made without departing from the spirit of the invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a printing apparatus, a vertically adjustable stand, a platform upon said stand, a table rotatably mounted upon said platform, said platform adapted to be ad justed upon an axis at an angle to the axis of rotation of said table, and supporting means upon said platform adapted to carry a printing film.

2. In a printing apparatus, a stand, a platform upon said stand, a table rotatably mounted upon said platform, said platform adapted to be adjusted upon an axis at an angle to the axis of rotation of said table, and supporting means upon said platform adapted to carry a printing film.
